The reasons why the hood of a new car gets very hot are as follows: 1. Heat generation reasons: The temperature of the engine starts to rise rapidly just a few seconds after starting, because the engine needs to reach a certain temperature to perform optimally; The combustion of the gasoline and air mixture in the cylinders generates enormous heat as it rapidly burns and expands to drive the piston movement. 2. Hood heating: While driving, the wind generated by speed and the fan blow the heat from the radiator into the engine compartment, and since the hood is made of metal, it heats up quickly; The heat from the engine operation, including the radiator's heat, is dissipated to the hood. As long as the temperature gauge on the dashboard does not indicate overheating, there is no problem.
